Abstract

The utility model relates to a flow control valve, which comprises a valve plate assembly, which is pivot mounted on a valve shaft in an tube, wherein, the valve shaft is connected to a valve plate and the dimensions and shape of the valve shaft match the pipe diameter; a counterweight assembly, which is arranged outside of the tube and connected to one end of the valve shaft, and has a chamber or linking part to accommodate or support the counterweight, so that the counterweight can be adjusted along with flow variations in the tube to control the opening angle of the valve plate.

Description

Flow control valve

Technical field

The utility model is a kind of flow control valve, and particularly a kind of adjustment via counterweight makes fluid open the different amount valve block down in different flow, to connect self-regulating effect.

Background technique

In FLUID TRANSPORTATION, the size of flow is the main cause for influence operation, and as in the occasion of waste gas treatment, the flow of this waste gas is concerning processing rate and relevant outfit, be with, the control of flow is the problem for being worth discussion must face again.

Existing flow control, its method is a lot of, has through solenoid valve, and the release of pressure of increasing loop is arranged, be numerous, but basically, and even these are configured in design, install and adjust, or too complicated and cost height, or operation inconvenience, therefore, it has the space of improvement.

The model utility content

In view of this, the claimant is in line with the experience of being engaged in the ring worker all the year round, concentrates on studies, and the phase can overcome above-mentioned disappearance, through experiment repeatedly, firstly appears and makes [flow control valve] of the present utility model.

A kind of flow control valve, it comprises:

One valve block group, it is to be installed in the body by valve shaft is pivotable, and this valve shaft is linked to a valve block, and its size and shape is corresponding to caliber;

One weight set is to be located at outside the body, and is linked to an end of valve shaft, and its tool one room or the connection part for splendid attire or the supporting mass;

So that the weight adjustment of mass is being the opening angle of valve block in response to the tube fluid flow.

It is fixing or slidably or the solid or the liquid that flow that described flow control valve, the mass of room wherein or connection part institute's splendid attire or supporting can be.

Described flow control valve, a counterweight must be established in valve block below wherein.

Described flow control valve, valve shaft wherein are that valve block central authorities be located at mutually in horizontal stroke.

Described flow control valve, weight set wherein top must be established one and be adjusted plate and open its slotted eye, and tool positioning hole up and down again is so that for a positioning block location.

Described flow control valve, connection spare wherein are for being located at the body of rod slippingly with counterweight.Be further to disclose concrete technology contents of the present utility model, below in conjunction with graphic detailed description it.

Fig. 3 is valve block of the present utility model schematic representation when crack;

Schematic representation when Fig. 4 is a valve block standard-sized sheet of the present utility model.

Embodiment

As shown in the figure, basically, flow control valve of the present utility model is by a body 1, one valve block group 2, and a weight set 3 combines.

Wherein, body 1 is to be prior art, its objective is for fluid to pass through, and claims fluid, can be gas, and even the liquid solid particle, and this body 1 is with respect to valve block group 2 its tool one input end and output terminals, and only this is that existing skill is not so intend going to live in the household of one's in-laws on getting married.

Valve block group 2 is the valve blocks 22 that linked with it by a pivotable valve shaft 21 and that is linked to body 1, the relevant position of this valve shaft 21 and valve block 22, can be in central authorities or position up and down, and for making it can be normal pass and increase resistance, thus establish a loading 23, into person is arranged especially, the shape of valve block 22 and size are for caliber, shown in the utility model embodiment, be for square, only not as limit.

Weight set 3 is to be located at outside the body 1, and it is linked to an end of aforementioned valve shaft 21, the top of this weight set 3, be to be a rectangular adjustment plate 31, the below then is a counterweight member 32, adjust 31 of plates and offer a rectangular board slot 311, and on the adjustment plate 31 of upper and lower, then opening some positioning holes 312, is adjustable location so that supply a positioning block 313, and counterweight gold 32 its inside are tool ccontaining 321 then, but and splendid attire configuration thing 322, this mass 322 can be liquid or solid connection part, is located at the body of rod as the counterweight with slip, so that this counterweight can move in response to hydrodynamic pressure.

Please consult graphic again, the utility model can be by the weight adjustment of mass 322, to determine valve block 22 in the degree of opening that is subjected under the hydrodynamic pressure, as shown in Figure 2 when implementing, be to be complete closed state, shown in Figure 3, be to be crack state, and shown in Figure 4, be to be the horizontal full-gear of valve block 22, in addition, also can be via the weight adjustment of loading 23, to adjust the opening angle of valve block 22 when stressed.

So, via enforcement of the present utility model, its have the use occasion looked and via weight set or loading to adjust effect in response to flow, again when counterweight adopts liquid, after tube fluid pressure or flow velocity reached setting value, valve can be opened slightly, this moment valve rod thereby rotate angle slightly, the liquid of counterweight can change the center of gravity and the moment thereof of counterweight along with the flows at angles of valve opening, with angle that increases valve opening and the speed of quickening valve opening.Its member is simple again, and cost is lower, and adjustment part simultaneously all outside body, is convenient to operation, a real quantum jump that belongs to flow control valve.

The utility model discloses, and is a kind of of preferred embodiment, and patent protection category of the present utility model is not all taken off in Ju Bu change or modification and come from technological thought of the present utility model and be easy to know by inference by the people who has the knack of this technology such as.
